Bentley vs. Harvard

Some of you may recall that Bentley won the “Fed Challenge” last year.  This involves teams from various colleges presenting their plan for monetary policy, and then responding to questions from Fed officials.  This year Bentley came in second to Harvard in the regional competition, which was the same outcome as two years ago.   Harvard went on to win the nationals.  Basically it’s Bentley and Harvard, and then a bunch of also-rans.  The New England regional is by far the toughest in the country, as Bentley had to beat MIT, Yale, Dartmouth and Brown to finish second.  A second place finish here is essentially a second place finish nationally.  So congratulations to the following students who so ably represented Bentley:

Edith Joachimpillai, James Cruise, Nick Fahmie, Monika Aderbauer, Yulia Podolny, Alfred Amasanti, Matias Bojanic Silvestro, Brett Kirkland, Alex Nocella, and Ross Sabasteanski.

My colleagues David Gulley and Aaron Jackson advised the team.

I suppose if Bentley and Harvard keep dominating the competition it will eventually start to seem unfair, as when the Celtics and Lakers dominated the NBA.  But I don’t think anyone can begrudge Bentley its success, as we clearly represent the underdogs. When I moved from Wisconsin to Boston in 1982 I stayed a Green Bay Packer fan—how can you not favor the small working class town?  No matter how many Super Bowls the Packers win they’ll never be seen in the same light as the Yankees/Cowboys/Lakers.  For sports fans, there’s nothing better than being able to enjoy total domination and not having to feel guilty about it.

This year Bentley’s team defended NGDP targeting.  I’m told by someone who attended the competition that judges seemed to challenge Bentley’s proposal more aggressively than Harvard’s (price level) proposal.  Hmmm, I wonder what that might mean?  In fairness, I was also told that Harvard’s team was very good this year.

I just taught my last class of the semester, and had the best group of students that I have ever taught.  (I teach monetary economics to several sections of Eco-Finance majors.)  Bentley has upgraded quite a bit over the past 20 years, as evidenced by much higher incoming SAT scores.  Local employers already know that Bentley students are an underrated asset.  Since Bentley is not (yet) as well known nationally as the Ivy League schools, I want to alert potential employers in other regions not to overlook our grads.  Not only are they excellent students, but they also tend to have very good attitudes.  Most don’t come from wealthy families, and they don’t have that “prima donna” attitude that one sometimes finds at other schools.  What other schools?  Let’s just say my students have never walked out on my class (except perhaps for a bathroom break.)

So employers should look for Bentley students, especially those from the “hard” majors (which I’d better not identify, in case any profs from the non-hard majors read this post.)

PS.  News of my blog’s success has finally reached the upper levels of Bentley, and my face was put on the home page (I don’t know for how long, it may be down by the time you read this.)

PPS.  I’m way behind on comments, but do plan to attack them soon.

Inflation targeting is a very bad idea

Mark Sadowski triggered an interesting discussion in a previous thread with the following comment about the UK:

The HICP was up 3.2% yoy in November. The core HICP was up 2.5% yoy in November. The HICP at constant tax rates was up 1.5% yoy in November. There is no “core HICP at constant tax rates”, but simple subtraction suggests that if there were one, it would be up by 0.8% yoy in November. Which means all the hysteria about inflation in the UK is a lot of nonsense.

Now I think we all agree price level targeting is superior to inflation targeting, and that NGDP level targeting is better still. But if you are going to target inflation rates than you should at least be targeting a measure of “inflation inertia”. The headline HICP in the UK is seriously skewed by the volatile energy and food component and the two VAT increases. Using the correct measure of inflation inertia, the real danger in the UK right now is deflation, not inflation.

All indications are that the Bank of England plans to tighten policy this May, with the idea of reducing aggregate demand growth in Britain.  At a time of fiscal retrenchment, it is hard to overstate how misguided that policy is.  And it will be justified by reference to the BOE’s mandate to engage in inflation targeting.  If you think that is bad macro policy, then by implication you need to rethink the utility of inflation targeting.  Here’s another way of stating how confused people are about stimulus.  Suppose it is a good idea for the BOE to be raising rates in May.  In that case, if it were true that fiscal retrenchment reduced the UK’s GDP in Q4, then that would be good news.

Mark’s comment points to one of the most serious problems with inflation targeting—there are all sorts of different inflation rates that people can point to.  Headline inflation, inflation without food and energy, inflation holding interest rates fixed, holding the VAT fixed, etc.  This creates a “gap” or grey area, where it is not clear whether the central bank should ease or tighten.  In contrast, NGDP targeting is crystal clear.  There is only one NGDP.  If the UK were doing NGDP targeting, there would be no discussion of tightening in May, indeed they might ease by cutting rates a quarter point, or doing more QE.

Some liberals argue that this problem can be solved with fiscal stimulus.  Not so.  Fiscal stimulus works if and only if it raises AD, and by implication inflation (the SRAS is never completely flat.)  If the central bank has the wrong inflation target, no amount of fiscal stimulus can boost AD.  But additional fiscal stimulus can very much hurt AS.  Indeed Britain has raised the top rate to 50% because of all the fiscal stimulus under the previous Labour government.  This takes away Britain’s one big supply-side advantage over the continent, lower taxes on high-paid professionals in the City.  Tight money and high taxes are a toxic combination.  Just ask Herbert Hoover.

Two years ago I pleaded with Obama to talk to Christy Romer.  I speculated that she favored monetary stimulus, and in another post I asked if Larry Summers was blocking access to the President.  It was certainly bizarre to see Obama let 3 Fed seats lie empty for an extended period of time; he clearly didn’t understand the importance of monetary policy.  In a new column in the New York Times, Christy Romer confirms my suspicions.  She was aware of the need for monetary stimulus.  She does understand that it can be effective at the zero bound.  She does understand the importance of level targeting.  If you put her and Larry Summers in a room together, most people would find Summers to be the far more impressive figure.  I’d guess that President Obama did as well.  Big mistake.

The commenter Ram provided the Romer link, and had this to say:

She has called for more monetary expansion before, but this is the clearest she has been about what she has in mind, not to mention how urgently monetary expansion is needed. It makes me wonder whether Prof. Sumner’s old post about Larry Summers being the Dick Cheney of the Obama administration might have some merit. Romer clearly supported and supports fiscal stimulus, but I seem to recall Larry Summers discussing the need for a large, government spending-oriented fiscal stimulus in mid-2008, before the bottom truly fell out of the economy. Maybe Romer was insisting on the importance of standing behind good monetary policy, so Summers deliberately kept her out of the inner circle. Hard to know, but it’s remarkable that she’d make this dramatic of a pivot so soon after leaving the White House.

There’s an easy way to tell unsophisticated old Keynesians from the more sophisticated new Keynesians.  Do they call for fiscal stimulus when interest rates are positive.  Even Krugman admits that there is really no case for fiscal stimulus until rates fall to zero.  In September 2008 rates were at 2%, and the Fed refused to cut them after Lehman failed because they were worried about inflation.  Indeed a month earlier some at the Fed wanted to raise rates (and I believe the ECB did raise rates.)  In that environment fiscal stimulus does nothing.

But I don’t want to be too hard on the old Keynesians.  When central banks around the world are this confused and incompetent, it’s not hard to see why people grasp for fiscal stimulus out of sheer frustration.  Most people don’t have a clue as to how monetary stimulus works, or why it neutralizes fiscal stimulus (especially why it does so at zero rates.)  Fiscal stimulus is really easy to grasp at an intuitive level.  Throughout history, only a tiny number of economists have intuitively grasped the incredible power of monetary stimulus (even at zero rates) and also understood the need for monetary stimulus when NGDP is inadequate.  Irving Fisher was one and Milton Friedman was another.  Lots of people are aware of the power of monetary policy.  Lots of people understand the need for stimulus.  But damn few can see both.  And that’s why we are where we are.

BTW:  A long time ago I promised to post the video of Bentley’s team winning the Fed Challenge.  It is finally available:


Bentley triumphant

A few weeks back I reported that our debate team had triumphed in the regional Fed Challenge, topping lesser known schools like Harvard, Yale, Dartmouth and MIT.  Today I’m very pleased to report that our team has emerged victorious from the national competition in Washington DC.  As Vice President Joe Biden would say, “this is a BFD.”

I know what you are thinking; it is unfair that other schools had to compete with students who have been taught by the creator of TheMoneyIllusion.  Unfortunately, I can’t take credit for this one.  My colleagues David Gulley and Aaron Jackson set up the program and do most of the coaching.  Of course most of the credit goes to the students themselves.  Once again, here is the list of students who vanquished the competition from universities in the Boston area whose students hardly know we even exist:

Christina J. Harstad

Satyajeet Jadhavrao

Pranay Kumar Jain

Peter Jurik

David Norrish

Maximillian Barco

Shohana Jannat

Victoria Lee Tran

Everyone likes a David vs. Goliath story; surely there must be some Hollywood producers interested in a story about how an unlikely group of students from Bentley were able to defeat those overconfident rich kids from the Ivy Leagues.  Something inspirational like Breaking Away, or the film about the spelling bee.

Now if only the Fed would adopt their policy recommendations.

BTW, I’m told a YouTube video of the competition is forthcoming—I’ll let you know.  I’ve also been told that in past years the winning team was awarded a substantial sum of money, but this year the prize was dropped.  Just imagine the team’s disappointment when they heard that news, after all their hard work preparing for the competition.  At first I thought that perhaps with all the recent QE, the Fed had run out of money.  But then I remembered that as long as they have paper and green ink, they never run out of money.

Later I was told that in previous years the prize was awarded by Moody’s, but this year Moody’s decided to drop the award.  Why could that be?  Perhaps their sales are down after questions were raised about all those sub-prime mortgage bonds that were rated AAA.  But no, Moody’s earned $189 million in just the 3rd quarter, on revenues of $513 million.  That’s one of the highest profit margins in corporate America.  After all the bad publicity, what better way for Moody’s to restore their image than by supporting these plucky underdogs?

Or if Moody’s won’t come through, perhaps some other corporate titan would like to get the good publicity one could expect by supporting our team.  You’d be supporting healthy collegiate competition as it was originally intended, before universities became unpaid farm teams for pro sports.  Competition, learning, public policy engagement; supporting our team would be an ideal way of burnishing your corporate image, particularly if you are one of those companies that made some, er, unfortunate choices around 2006-07.

PS.  Recently I’ve been extremely busy.  (No, I didn’t goof off because of vacation.)  I hope to catch up on old comments tomorrow and post something new.

Bentley rulz

The Fed Challenge is a monetary policy debate held each year for teams of undergraduate college students.  Our team usually does pretty well, but yesterday’s performance was especially noteworthy.  They competed in the Northeast semifinals against some obscure colleges such as:

Harvard, Brown, Dartmouth, MIT, Yale, Tufts, Framingham, Salem, Middlebury, Bryant, BC, BU, Bridgewater, Clark, Northeastern, WNEC, Quinnipiac, UNH

And won.  Which means it’s on to the national contest in DC.

Congratulations to our team:

My colleagues David Gulley and Aaron Jackson have done all the work setting up our team and advising them, but I did get to meet them a couple times and saw their practice session.  One of the team members (David Norrish) offered a fairly persuasive argument against NGDP targeting.  He said something to the effect; “Is it really wise to have the largest economy in the world experiment with a policy that has never once been tried anywhere else?”

Because I am a pragmatist, I found this critique pretty impressive.  After all, inflation targeting was first pioneered in small economies like New Zealand.   And it got me thinking about NGDP targeting in small countries.  Suppose there was a huge rise in the world price of copper, and as a result the Chilean copper industry went from 10% of NGDP to 15% almost overnight.  Under strict NGDP targeting, this would require the non-copper parts of the Chilean economy to shrink by 5% of GDP.  I suppose you could argue that workers should be reallocated to the copper mining industry.  But that industry may be capital intensive, and/or the supply may be rather inelastic in the short run.  Some ideas:

1.  This thought experiment suggests NGDP targeting might work better in very large and diversified economies where no single industry is dominant.

2.  This example suggests Bill Woolsey might be right about nominal domestic final sales being superior to NGDP, after all, most Chilean copper is exported.

3.  Recall that I once argued nominal wage targeting was theoretically superior, but NGDP was a pragmatic compromise.  This example shows where NGDP is no longer a good proxy for nominal wages.

4.  It might be better to set the NGDP target a bit further out in the future—say a policy of targeting 2-year forward NGDP (as some of my commenters suggested.)

The bottom line is that I don’t expect NGDP targeting to be adopted by a small country.  Nominal domestic final sales is still a possibility, however.

PS.  It’s especially gratifying beating the school portrayed in The Social Network.  Let’s see if Greg Mankiw does a post on this.  🙂

Update:  In the comment section Bill Woolsey mentioned that he favored targeting nominal final sales, and my example was actually referring to nominal final purchases.  Also in the comment section George Selgin observed that this post raises the question of optimal currency zones.  Or perhaps I should say optimal monetary policy zones.  I think he is right, but I also think the dollar zone is smaller than generally perceived.  For instance, many would include China, despite the fact that the yuan is up about 3% in recent months, and over 20% since 2005.  It’s clear China has raised the yuan precisely because they wanted to avoid the high inflation that would result from a dollar peg.  The three or four countries that actually use the dollar would definitely qualify, but they are quite small.  Those with rigidly fixed rates are also part of the dollar zone, although I believe most of them are also fairly small.  Are there any large countries that have rigidly pegged their currencies to the dollar for a long period?
